ABSTRACT={This paper presents a self-contained introduction and implementation
description to a simulation system for modeling simultaneous action and continuous
processes (Hendrix, 1973). The essence of the system is described by a portion
of its abstract: ``A new methodology for the construction of world models is
presented. The central feature of this methodology is a mechanism which makes
possible the modeling of (1) simultaneous, interactive processes, (2) processes
characterized by a continuum of gradual change, (3) involuntarily activated
processes (such as the growing of grass) and (4) times as a continuous phenomena.''
and by a recent review, Gains (1975): ``This is a fascination paper that will
be of interest outside the ``artificial intelligence'' (AI) context in which
it is written, from those concerned with simulating and controlling multi-element
systems to those interested in operational definitions of concepts such as
causality.'' Three robot world models are incrementally developed, each introducing
a new modeling concept. World models, including a robot world (with sample
output), electrical world, and a Turing world are also presented. The interactive
operating environment represented permits the user to inspect and alter the
run-time structure. A detailed account of the implementation is presented.}
